MAGAZINE FOR TYPE-SETTING MACHINES.

To all whom it may concern:

Be it known that 1, JOHN J. HUMMEL, a citizen of the United States, anda resident of Spokane, in the county of Spokane and State ofWVashington, have invented a new and Improved Magazine for Type-SettingMachines, of which the following is a full, clear, and exactdescription.

Among the principal objects which the present invention has in view are:to provide a magazine for holding type in position for delivery to atype setting machine having a feeding attachment adapted to mechanicallydeliver type pieces to the type setting machine; to provide a feedingmechanism for the said type graduated to the thickness of the type beinghandled; to provide a simple and etlicient construction for attachingthe magazine to the font frame of a type setting machine; and to providea magazine constructed in such manner as to be rapidly and readilyplaced in position for refilling.

One embodiment of the present invention is disclosed in the structureillustrated in the accompanying drawings, in which like characters ofreference denote corresponding parts in all the views, and in whichFigure l is a vertical longitudinal section of a magazine constructedand arranged in accordance with the present invention, showing inconjunction therewith a fragment of a type setting machine and theextracting mechanism thereof; Fig. 2 is a vertical cross section of themagazine taken on the line 2-2 in Fig. l; and Fig. 8 is a vertical crosssection of the magazine taken on the line 3-3 in Fig. l.

The magazine herein illustrated and described is used in conjunctionwith a type setting machine for which I have made application for patentco-pending herewith. The said type setting machine is provided with anextracting mechanism having a type holding table X provided with jawswhich spread to receive the type pieces as delivered from the magazine.The delivery is accomplished by ejecting the successive type pieces bymeans of an ejecting mechanism forming part of the magazine, and beingactuated by a trigger or striking bar Y protruded into the path of theactuating mechanism for the said magazine. The striking bar Y is, in thetype setting machine referred to, projected from each of the typeextractors the same distance. When projected they Specification ofLetters Patent.

impinge upon the free end 4 of a bell crank lever 5 with which each ofthe magazines is provided, irrespective of the size or shape of thevarious characters carried thereby. Each of the magazines is assigned acertain character, and none other is placed in the magazine, thereforeall of the letters in the said magazines are uniform in thickness.Corresponding to the thickness of the type pieces are the ratchet teethof a rack bar 6, each bar differing from every other in the length oftheratchet teeth, and corresponding and co-relating to the length of thefree arm 4 of the bell crank'5. The length of the free arm 4 of the bellcrank 5 governs the pull on the arm 7 of the said bell crank. The arm 7,by means of a wire 8, is connected to a pendant arm 9 extended from theback of the rack bar 6. The bell crank is pivoted at 10 between thesides of a groove 11 at the delivery end of the magazine. The rack bar 6is mounted in an open groove 12 extending longitudinally under the typepieces Z. The type pieces are suspended and guided by a flange 13 formedin the side wall 14 of the magazine, and over which the nicks W of thetype pieces fit. The rack bar 6 is supported by links 15, 15 pivotallymounted at 16, 16 in the frame of the magazine and forming a rockingconnection for the said rack bar.

Between the sides 14, 14 of the magazine is formed an open runway inwhich the type pieces and a thrust block 17 are mounted. The thrustblock 17 is provided with a nick similar to the nick W formed in thetype pieces Z. The block 17 is provided with a recess 18 openingdownwardly and rearwardly, and in which are pivoted at 19, pawls 20 and21. Both of the pawls 20 and 21 are connected by means of connectingrods 22 with leaf springs 28. The springs 23, 23 are fixedly secured at24 to the block 17.

The pawls 20 and 21 engage the teeth of the rack bar 6 and the teeth 25formed in the fixed structure of the magazine. The teeth in the rack andthe teeth 25 in the fixed structure correspond in shape and length. Theobject in the use of the two is to prevent the backward thrust of theblock 17 and the column of type carried thereby, when the type is beinglifted for delivery. This is accomplished by the pawl 21 engaging one ofthe fixed teeth 25 with every forward or delivery movement of the rackbar I mounted in the said block.

adapted to 6. Both the pawls 26 and 21 are moved to.

of the bar 6, the bell crank 5 is placed in operative position where itis arrested by a stop 27, which further serves to limit the backwardstroke of the bar 6.

The magazine is temporarily mounted on the back plate V ofthe fontcarrying frame disclosed in the co-pending application above referredto. For this purpose the body is provided with plugs 28, 28 which "fitwithin recesses provided in the said frame and having screw-threadedholes receive the screw-threaded shanks of wing nuts 29, 29. Theperforations provided in the frame V are elongated to pass the wing nuts29, and are narrowed so that when the wing nuts are turned, as shown inFig. 3, they serve to hold the magazine firmly in position on the saidframe.

The operation of the device is as follows: As above stated, the arm A ofthe bell crank 5 is graduated to produce a movement of the column oftype pieces Z equal to the thickness of said type pieces. With theoperation of the type setting machine described in the above citedapplication, the striking bar Y impinges upon the arm 4 of the bellcrank 5, causing the same to rock I to draw downward the arm 7.

The arm 7 of the bell crank 5 is connected by means of the wire 8 withthe pendant arm 9 in such manner that with the downward pull of the arm7, the pendant arm 9, and rack bar 6 connected therewith, are likewisedrawn toward the delivery end of the magazine. Moving thus, the rack bar6, the column of type pieces and the thrust block 17, are like- "WlSBmoved by reason of the engagement between the said rack bar and the pawl20 The result of the movement of the type column and thrust block is topresent one of the type in the path of the striking bar, causing theremoval of the same from the magazine and into engagement by the typeholder X. The striking bar having passed from engagement with the bellcrank 5, the coiled spring 26 is permitted to retract the bar 6. Thethrust block 17 is at this time held from retraction, by the engagementof the pawl 21 with the teeth 25 of the fixed magazine structure. Thepawl 20 yields to pass the teeth of the rack bar 6, one tooth passing,to engage the same for the next succeeding delivery of type, and theforward movement of the rack bar '6. The above action is repeated untilthe column of type is partially or entirely exhausted, the block 17advancing from the rear to the delivery end of the magazine tooth bytooth of the bar 6, and by movement equaling the thickness of the typecarried by the said magazine. \Vhen the magazine is exhausted topredetermined extent, it is removed from the frame V by turning the wingnuts 29, 29 in alinement with the perforations formed in the said frame.A duplicate magazine is immediately placed in position, and the typesetting machine continues in its operation. The magazine which has beenremoved is lifted by retracting the block 17 to the rear end. To do thisit is only necessary to compress the springs 23, 23 so that by means ofthe connecting rods 22, 22 the pawls 20 and 21 are lifted fromengagement with the teeth 25 and the rack bar 6. In this position theblock may be freely retracted to the rear end of the magazine. Inplacing the type in the magazine they are threaded from the forward endthereof, the nicks of the type being extended over the flange 13 formedin one of the sides 14 of the magazine.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:
